My Usual AMO Blurb: The Atlantic Multidecadal Oscillation as calculated by the NOAA ESRL is North Atlantic SST anomalies that have been detrended. Since OI.v2 SST data begins in November 1981, it does not seem appropriate to use a 28-year trend on a cycle that lasts about 60 years, so I am NOT presenting the AMO.

Using North Atlantic SST anomalies as a reference, the AMO is still rising from its low this year in February. Scroll down for the North Atlantic SST anomalies.

NOTE ABOUT THE DATA

The MONTHLY graphs illustrate raw monthly OI.v2 SST anomaly data from November 1981 to July 2009.
